KNOWV ALL MEN BY TH ESE PRESENTS: l

That we, CERLES B. LONG and WILLIAM A. N.` LONG, both of the city andcounty of Worcester, and Commonwealth of Massachusetts, lhave inventedcertain new and useful. Improvements in Rings and wedo'hereby declarethat the following isa full, clear, and exact description of the same,reference being had to the accompanying drawings, forminga part of thisspecification, in which- Figurel represents'a perspective view of ourimproved ring.

Figure 2 represents a side view, 'and I Figure 3 represents a vertical'section through the upperpart of the ring. v

To enable those skilled in the art to which our invention belongs tomake and use the same, we will proceed to describe it more in detail. 4

i The object of our present invention is the production of acombination-ring, of peculiar construction, and

which shall serve not only as an ornament, hut as aconvenient ,cutterfor cutting off threads used in' sewing, tying up of pnekagesyand forother similar purposes. l l Y In the drawings, the ring part A is shownwithI a neck, e, having a cap, B. The neck a has als'lit or opening madethrough it for the reception of the peculiarly-shaped'knife o r cutter6. i

The under side of cap B, together with the upper part G of the ring partA, is slightly channelled or cu out on aline with the slit in the necka', whereby the knife or cutter b, when it is slipped into place in theslit or opening in the'neck a, is supported at the top in the slit inthecap B, and at the bottom in the slit in the part C of the ring. v y

The cutter or'knife b is retained in place or position by a. rivet, e,as fully indicatedin the drawings.

The cap B may be made in any desired f orm, and it may be mounted with astone or diamondipreierred.

The cutter or knife b is made with inclined edges d cl, which are to besharpened. The knife or cutter b can be tempered and sharpenedbefore itis slipped into place, and when dulled by long use, can be quicklyremoved for` sharpening. vAs no soldering is required in securing theknife, the danger and liability of drawing the temper by such anoperation are entirely obviated. Y

'lhe knife or cutter b is so secured by the cap B as scarcely to benoticed except on close inspection.

By drawing the thread or twine against either of the inclined edges d,it is quickly cut or severed.

It is unnecessary for us to particularize the utility and greatconvenience of our invention, especially in stores and packirigroougs,snce'the advantages will be apparent to all. l

Having described our combination-ring, what we claim therein as new andof our invention, and desire to secure by Letters Patent, isl Thecombination of.tl1e peculiarshaped kniieor cutter b. with the slottedneck a, cap B, and part C of the ring,` substantially as and for thepurposes set forth.
